Overview
The COM210 modem enabled communications between a computer and a Campbell data logger via a public switched telephone network. A Hayes-compatible modem was required at the base-station computer while a COM210 was connected to the data logger at the field site. The COM210's wide operating temperature range and minimal power requirements made it ideal for use at remote sites.
Technical Description
The COM210 modem enabled communications between a computer and a Campbell data logger via a public switched telephone network. A Hayes-compatible modem was required at the base-station computer while a COM210 was connected to the data logger at the field site. The COM210's wide operating temperature range and minimal power requirements made it ideal for use at remote sites.
Note
Historically, the 10704 Power Adapter was available for connecting the COM210 to the CR500 with s/n 1764 or lower, and the CR10 with the silver or 8032 black wiring panel. The adapter applied a constant 12 V to the COM210's serial I/O. This power adapter is no longer available.

Power Considerations
The COM210 consumed 120 microAmps quiescent, 160 mA active (max). The data logger's power supply was sufficient for most applications.
Cabling
Data Logger-to-COM210
An SC12 cable was provided for this purpose.
Phone Line-to-COM210
Typically, a length of phone line was run from the telephone company's junction box to the COM210s surge protector, and then to the Ground, Tip, and Ring terminals on the COM210. Alternately, if adequate surge protection was provided by the telephone company and the junction box supports it, a length of telephone wire with RJ11C connectors (#2365) could be run directly from the junction box to the socket on the COM210.
Surge Protection
If the local telephone company did not provide surge protection, either the 6362 or 4330 surge protector needed to be used. See "Ordering Info" tab for more information.
Enclosures
The COM210 required a desiccated, non-condensing environment; a Campbell Scientific enclosure was recommended. Grommets and screws were provided to attach the COM210 to the backplate of our enclosures.
Software
LoggerNet and PC400 software are compatible with the COM210. Both of these software packages provide automated error-checking or user-initiated contacts. LoggerNet also supports scheduled contact times. Our software can run unattended allowing the user to take advantage of lower off-hour telephone rates.
